Abstract:
Transcatheter atrial septal defect (ASD) closure has proven to be safe and effective, and it is rapidly becoming the standard treatment for secundum-type ASDs. However, device embolization occurs in about 0.55% of cases, regardless of ASD and device size and/or physician's expertise. Percutaneous retrieval of the embolized device is possible in about 50% of cases, and several techniques have been described, including the use of large sheaths, gooseneck snares, or bioptomes. This is the first successful and reported case of retrieval of an embolized amplatzer septal occluder (ASO) from the left ventricle that was achieved by using a modified snare technique. This was done after an unsuccessful attempt at retrieval with a bioptome that led to a never previously reported complication. Of the 32 reported cases of ASO embolization, percutaneous retrieval was successful in 16 cases (50%) and none were obtained following left ventricular embolization. Even in experienced hands, the observed rate of embolization when using an ASO device is not negligible. Percutaneous retrieval is also possible from the left ventricle but in some cases nonstandardized devices and strategies may be required.
